Cash 4 Gold & Diamonds buys natural, cut and polished diamonds in Downtown Los Angeles—any size, any shape, loose or set in jewelry.

Have a substantial stone or diamond collection? See our large natural diamond buying guide for the shapes, jewelry and documents to bring.
Visit our Downtown Los Angeles Jewelry District location for an in-person diamond evaluation. We examine the characteristics that affect a diamond’s resale value, including carat weight, cut, color, clarity, shape, condition, certification, and current market demand.
If your diamond has a GIA grading report or other documentation, bring it with you. Documentation can help us verify important characteristics of the stone, but we can also evaluate diamonds that do not have their original paperwork.
After evaluating your diamond, we can provide an offer based on the specific stone and current resale market conditions. There is no obligation to sell simply because you receive an evaluation.

Understanding Your Diamond Before You Sell
Selling a GIA Diamond in Los Angeles
A GIA grading report can provide important information about a diamond, including its carat weight, color, clarity, cut grade when applicable, measurements, proportions, and identifying characteristics.
If your diamond has its original GIA report, bring the report with you. We can use the grading information together with an inspection of the actual diamond and current market conditions when evaluating the stone.
A grading report does not by itself determine the amount a buyer will pay. Two diamonds with similar laboratory grades can have different resale demand and market values depending on characteristics such as shape, measurements, cut quality, fluorescence, condition, and current buyer demand.
How Is a Diamond’s Value Determined?
There is no single price-per-carat number that accurately values every diamond. Several characteristics work together to influence resale value.
Carat Weight
A diamond’s carat weight measures its weight, but larger diamonds do not simply increase in value at the same rate per carat. Size thresholds, quality, shape, and market demand can significantly affect value.
Cut
Cut and proportions affect how effectively a diamond reflects light and can influence both appearance and market desirability.
Color
For many colorless diamonds, less visible body color can affect grading and market value. Fancy-color diamonds are evaluated differently.
Clarity
Clarity considers inclusions and blemishes, including their size, number, position, and visibility.
Other important factors can include diamond shape, measurements, fluorescence, laboratory report, condition, brand or setting, and current wholesale and resale demand.
Sell Your Diamond Engagement Ring in Los Angeles
If you are selling a diamond engagement ring, we evaluate both the center diamond and the ring itself. Depending on the piece, factors such as additional diamonds, precious-metal content, designer branding, condition, and documentation may also affect the overall evaluation.
Bring any GIA reports, receipts, original boxes, designer documentation, or other paperwork you still have. These items are helpful when available, but they are not required for us to examine your jewelry.

Get an Item-Specific Diamond Offer
When comparing diamond buyers, focus on the final offer for your actual diamond rather than relying only on an estimated price given before the stone is inspected.
A diamond’s value cannot be determined accurately from carat weight alone. The complete characteristics of the diamond and current market demand matter.
Ask how the offer was determined and compare final, item-specific offers before deciding where to sell.
Local Diamond Buyer vs. Consignment or Auction
There are several ways to sell a diamond. The right choice depends on whether your priority is convenience, speed, or potentially waiting for a future buyer.
Direct Local Diamond Buyer
A direct buyer evaluates the diamond and can make an offer for the item. This allows the seller to decide whether to accept an offer without waiting for the jewelry to sell to another consumer.
Consignment
With consignment, the jewelry is generally listed for sale and the seller waits for another buyer to purchase it. Terms, fees, and timelines vary by company.
Auction
Auction may be appropriate for certain rare, important, or highly desirable pieces. Auction fees, timing, reserves, and results vary depending on the auction house and item.

Frequently Asked Questions About Selling Diamonds in Los Angeles

Where can I sell a diamond in Los Angeles?
Cash 4 Gold & Diamonds evaluates diamonds at our location in the Downtown Los Angeles Jewelry District. We evaluate loose diamonds, engagement rings, diamond jewelry, estate pieces, and GIA-graded diamonds.
Do I need a GIA certificate to sell my diamond?
No. A GIA report or other laboratory documentation is helpful when available, but you can still bring a diamond for evaluation without its original paperwork.
What determines how much my diamond is worth?
Diamond value can depend on carat weight, cut, color, clarity, shape, measurements, condition, laboratory grading, fluorescence, and current resale demand.
Do you buy loose diamonds?
Yes. We buy loose natural polished diamonds of any size and shape, as well as natural diamonds in engagement rings and other jewelry. We do not buy laboratory-grown or uncut diamonds.
Can I sell an engagement ring?
Yes. We evaluate diamond engagement rings and consider the center stone as well as relevant characteristics of the setting, additional stones, precious metals, branding, condition, and documentation.
Should I bring my GIA report?
Yes, if you have it. Bring the original GIA report and any other relevant documentation, receipts, boxes, or designer paperwork that may help identify the item.
How do I compare offers from diamond buyers?
Compare the final offer for your actual diamond and ask how the buyer determined the offer. Estimates given before physical inspection may change after the diamond’s characteristics are verified.
Is a diamond evaluation the same as an insurance appraisal?
Not necessarily. An insurance or replacement-value appraisal serves a different purpose from an offer to purchase a diamond in the current resale market.
For general questions about visiting or selling jewelry, see our FAQs.
